Other articles where Stope is discussed: mining: Underground mining: …of extracting ore are called stopes or rooms. There are two steps involved in stoping. The first is development—that is, preparing the ore blocks for mining—and the second is production, or stoping, itself. Ore development is generally much more expensive on a per-ton basis than stoping, so that every effort…
Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the surface.

Underground mining is carried out when the rocks, minerals, or precious stones are located at a distance far beneath the ground to be extracted with surface mining. To facilitate the minerals to be taken out of the mine, the miners construct underground rooms to work in.
In any discussion of Methods of Underground Mining Comparison, one is repeatedly confronted with the difficulty of dealing with so many variable conditions. It is not an exact science and in the choice of a method each varying factor has a certain weight, which, in many cases, experience alone can determine.
technologies currently being employed is the mechanisation of the mines’ underground operations. According to Croll (2004), mechanisation is the use of powered machinery to replace manual labour. Within the mining context, mechanisation refers to human operators being given machines to assist them with stoping functions.
Underground mines have changed their operation systems in accordance with the evolution of equipment, the system and method of mining. Transport is also of critical importance in underground mines as is the mining operation itself. The underground transport system of ores, materials, equipment and persons has been developed from
Author: Mike Neumann, Neumann Engineering and Mining Services Inc. (NEMS) Date: May 2010 Shrinkage stoping is a mining method used for steeply dipping, narrower ore bodies with self supporting walls and ore. It is an overhand mining method that relies on broken ore being left in the stope to be used as the “working floor” and to support the walls.

Platinum Mining Methods. How Is Platinum Mined : Originally pgm was extracted using “the narrow reef method” in which miners use handheld pneumatic drills to create holes in the reef into which explosives can be loaded. After the ore is released through blasting, it is removed using scrapers attached to wenches and transported to the surface.
